3. Introduction:
Why lean and agile
development at SAP?
Scheerer, Schmidt, Heinzl, Hildenbrand, Voelz 3

4. The previous development process resembled a stage-gate
approach
Scheerer, Schmidt, Heinzl, Hildenbrand, Voelz 4

5. The current process follows a Lean Product Development Flow
approach
How to efficiently deliver
innovative enterprise
software to customers?
Scheerer, Schmidt, Heinzl, Hildenbrand, Voelz 5

6. How do Scrum teams adopt
Agile Software Engineering
Techniques (ASET)?
Scheerer, Schmidt, Heinzl, Hildenbrand, Voelz 6

7. ASET as the missing link to effectively implement lean
development principles in large scale software companies
Pair programming,
Specific
test-driven development,
agile techniques
continuous integration,
ASET (Beck 2001)
refactoring
Teams with Scrum master,
Agile method
Scrum product owner, developers and
as process framework
an associated manager for
(Schwaber & Beedle 2001)
people development
Lean Principles Eliminate waste, build quality in,
Lean principles learn constantly, deliver fast,
(Poppendieck 2003) engage everyone,
Scheerer, Schmidt, Heinzl, Hildenbrand, Voelz keep getting better 7

8. Research Process

9. A great majority of the respondents generally confirmed
that they enjoyed the practices
Scheerer, Schmidt, Heinzl, Hildenbrand, Voelz 9

10. Two groups of adopters emerged within our study:
High vs. Low Adopters
Low Adopters
High Adopters
Scheerer, Schmidt, Heinzl, Hildenbrand, Voelz 10

11. Heterogeneous Adoption Patterns
Variations in Pair Programming Adoption Intensity
People Process
• Continuous value generation
• Broader knowledge base
• Fast feedback
• Quality awareness
Advantages • Avoidance of trivial errors
• Collaboration
• Intra-team discussion culture
• Team cohesion
• Inter-personal conflicts
• Stressful
Disadvantages • Lower development speed
• Synchronization of work
schedules
Scheerer, Schmidt, Heinzl, Hildenbrand, Voelz 12

12. Heterogeneous Adoption Patterns
Variations in Test-driven Development Adoption Intensity
People Process
• Increased focus on current task
• Increase of self-confidence
• Large test framework
Advantages through continuous
• Maintainability increase
feedback
• Increase of structuredness
• Interrupts free flow
• Effort for user interface tasks
Disadvantages of thoughts
disproportionately higher
• Painful transition
Scheerer, Schmidt, Heinzl, Hildenbrand, Voelz 14

13. Outlook:
Combining Design and Development
Scheerer, Schmidt, Heinzl, Hildenbrand, Voelz 16

14. Innovation = Desirability + Feasibility + Viability
Successful Business Model
Scheerer, Schmidt, Heinzl, Hildenbrand, Voelz 17

15. An Analytic Approach Doesn‘t Work for Enterprise Software
Scheerer, Schmidt, Heinzl, Hildenbrand, Voelz 18

16. Development Teams Need to Think Like Designers Sometimes…
Scheerer, Schmidt, Heinzl, Hildenbrand, Voelz 19

17. However, Design Thinking is No Rocket Science!
Scheerer, Schmidt, Heinzl, Hildenbrand, Voelz 20

18. Combining Design and Development: Lean and Design Thinking
Scheerer, Schmidt, Heinzl, Hildenbrand, Voelz 21

19. What are the 3 Things to Remember?
Scheerer, Schmidt, Heinzl, Hildenbrand, Voelz 22

20. Summary and Conclusion
1) Agile Software Engineering techniques help
teams to build enterprise solutions efficiently
2) In a large-scale Lean implementation ASET
brings agile practices into daily business
3) Design Thinking helps teams to find problems
worth solving and create innovative solutions
